Cosmic scalar fields with flat potential ∗
The dynamics of cosmic scalar fields with flat potential is studied. Their contribution to the expansion rate of the universe is analyzed, and their behaviour in a simple model of phase transitions is discussed. ∗Work supported by the research program FP52 of the Foundation for Fundamental Research of Matter (FOM). ∗∗e-mail: [email protected] The universe is observed to expand [1], and this ex...
متن کاملNew Type Scalar Fields for Cosmic Acceleration
We present a model where a non-conventional scalar field may act like dark energy leading to cosmic acceleration. The latter is driven by an appropriate field configuration, which result in an effective cosmological constant. The potential role of such a scalar in the cosmological constant problem is also discussed. ∗e-mail: [email protected] June 2006 During the last years, evidence of an accel...
متن کاملCosmic Acceleration, Scalar Fields and Observations
Conditions for accelerated expansion of Friedmann–Robertson–Walker space–time are analyzed. Connection of this scenario with present–day observations are reviewed. It is explained how a scalar field could be responsible for cosmic acceleration observed in present times and predicted for the very early Universe. Ideas aimed at answering whether is that the actual case for our Universe are descri...
متن کاملOne-loop Effective Potential for Scalar and Vector Fields on Higher Dimensional Noncommutative Flat Manifolds
The effective potentials for massless scalar and vector quantum field theories on D dimensional manifold with p compact noncommutative extra dimensions are evaluated by means of dimensional regularization implemented by zeta function tecniques. It is found that, the zeta function associated with the one loop operator may not be regular at the origin. Thus, the related heat kernel trace has a lo...
متن کاملDynamics of MSSM flat directions consisting of multiple scalar fields
Although often chosen because of simplicity, a single scalar field does not provide a general parametrization of an MSSM flat direction. We derive a formalism for a class of gauge invariant polynomials which result in a multifield description of the flat directions. In contrast to the single field case, the vanishing of the gauge currents yields an important dynamical constraint in the multifie...
